Both the problems might occur due to similar causes. Apart from accidents, poor hygiene and untreated cavities can make your teeth weak and more vulnerable to damage. Chips and cracks can also occur if you bite on something hard or get hit on your teeth directly while playing a sport.
Talking about the treatment procedure, they are slightly different. For chipped teeth, the treatment depends on the size and intensity of the damage. For small chips, smoothing and polishing your teeth will be enough. However, for bigger and intense chips, you might need solutions like crowns, fillings, etc. For larger chips, root canal therapy might be the only solution.
For smaller cracks, you might not need treatment at all. Your dentist will decide that after a thorough examination. But for a slightly larger crack, you would need a bonding procedure to hold the teeth together. In case the crack has damaged the tooth pulp, you might need root canal treatment followed by a crown.
So whatever might be the condition, it is essential to visit your dentist and seek immediate care and attention.
